To all whom t may concern." f

Be it known that l, Giusnrrn CANNEs'rI, a subject of the King oft Italy, residing at Bronx, inthe county of Bronx and State of kil'ewkYork, have invented newandy useful Improvements in Gutlet-Valves, of y.which the following is ay specification. y

This `invention relates to outlet valves for flush tanks and it consists inthe novel features hereinafter describedfand claimed.

yAnobject of the inventionis toy provide an outlet valve of simple and durable structure which mayl be easily `and (quickly manipulated to permit water to readily flow from a tank or otherreceptacle. With this objecty in view the valve includes a fitting adapted to be passed*k through thebottom of the tank or receptacle and which is provided at its upper portion with a` valveseat. vA. cylinder vis mounted 'upon the fitting and is provided at its sides withopenings and a water inlet is connected withthe upper yportion of the cylinder and above the openings therein.k A valve is movably mounted. in thc cylinder and is adapted to close against the seat of the fitting andis provided witha hollowstem. provided. at its upper end with openings. Means is provided uponrthe stem for guiding the same inthe cylinderr andfor closing the upper portion thereof at points above the openings in the cylinder. shaft is turnably mounted in the upper portionof the tank and is providedwith a crank, a pitman operatively yconnects 'the crank f with the valve stem and a weighted arm is connected withL the said shaft vand is `located beyond the sideof the tank andis adapted when swung to turn the shaft whereby the valve isyoperated.y y. A.

ln the accompanying drawing :kk- Figure 1 is a vertical sectional view .of theyoutlet valve. Fig. 2 is a detailed` elevational view` of the endfof theshaftfand arm mounted thereon. Fig. 3 is a -siderelevration valve proper and stem thereof. y y.

The rvalve mechanism includesa fitting 1 which is adapted to berpassed through the bottom y2 of atankor otherreceptacley flush pipe 3 may be' connectedlinqany suit-g able manner with theloiwer end of a fitting 1 at aypoint belowthe bottom 2.of the said receptacle. rllhe fitting 1 is providedat a point below the bottom v2 of the said recep tacle. ,Thetting 1 is provided `at a: point LbOYC thfbftOm 2 kwith alaterally disposed nipple 4 to which is connected an overflow of the y Y justably. mounted upon one end portion of pipe 5 the end of the saidv pipe extending up to a point above the normal level of the water in the tank of which the bottom 2 is a part. `.The fitting 1 is -provided in its interrorJ and in the vicinityl of its upper end with .a valve seat 6. A cylinder 7 is suitably attached to the upper endvof the fitting 1 and surrounds the valve seat 6. In the .present; instance the cylinder is shown screw threaded in the fitting. The said fitting is provided Ain the vicinity of its lower end and at its. sides with openings 8 and an inlet pipe 9 is ,connected with the upper end portion of the said cylinder. kA valve proper 10 is adapted to close against the seat 6 and the said/.valve proper is provided with a hollowstem, 11 which extends up into the cylinder 7 and which is spaced from the side walls thereof by an enlargement 12 made integralwith the stem and which bears at its outer surface against the inner surface of the cylinder 7 as best shown in Fig. 1 of the drawing. points above the enlargement 12 with openingsil and a rod 14 passes through a cap 15 mountedat the upper end of cylinder 7 and is secured atfits lower end to the upper end of the stem 11. A coil spring 16 surrounds thelower portion ofthe rod 14. and rests at its lower end upon the upper end of the stem 11 and when the stem is moved in an upward direction'the upper end of the said spring is adapted to encounter the under surface of the cap 15l whereby the upward movement of the stem 11 is cushioned. A shaft 17 isturnably vmounted in the upper portion of the tank of which the part 2 is a component and the said shaft is provided with acrank y18.. A pitman 19 is pivotally connected at one end with the crank 18 and pivotally` connected at its `other end with the rodlt as best indicated in Fig. 1 of the drawing. `An armf20 is Xed to the outer end' of the shaft 17 yand a weight 21 is adthe. saidk arm. A chain 22 is connected `with the' other end of the arm 20 and a handle 23 is attached to the lower end of the chain 22.

yThe operation of the valve .isk as follows. The weight 21 isy suiliciently heavy to normally bein the position asshown in Fig.y 2y

ofy the drawing and when this is the case yit isto be presumed that the tank of which the rbottom 2 is a part is sufficiently rsupf pliedwith. water. When itis desired to permit the water to flow from the tank the chain 22 is pulled by using the handle 23 whereby the shaft 17 is turned and the crank 18 is moved in an upward direction. This moves the pitman 19 vertically and in turn 5 the said pitman moves the rod 14 in an upward direction whereby the stem 11 is moved up within the cylinder 7 and the valve 10 is moved away from the seat 6. When this is done water immediately flows through the 10 openings 8 and down through the fitting 1 and the outlet pipe 2. The flow of the water through the openings 8 creates a suction or siphonage in the upper part of the cylinder 7 and consequently water is drawn up through the outlet pipe 9 and through the opening 13 and down through the stem 11 and into the fitting 1.

When the pull is removed from the chain 22 the weight 21 causes the arm 20 to swing back to its normal position whereby the shaft 17 is turned so that the crank 1S moves in a downward direction and assumes the position as shown in Fig. 1. This moves the pitman 19 and the rod 14 in a downward direction whereby the stem 11 is moved down in the cylinder 7 and the valve proper 10 is seated against the seat 6. However the water continues to flow through the outlet 9 and thence through the opening 13 and through the stem 11 into the fitting 1 and out through the outlet pipe 3 until the water in the tank is at a level below the lower end of the outlet pipe 9. As soon as the water level descends below the lower end of the outlet pipe 9 the suction or siphon is broken and water ceases to flow from the tank through the outlet pipe 9 and the cylinder 7 as hereinbefore described.

During the ow of the water if at any 40 time there should be an excess of water entering the tank, the eXcess may pass from the same through the pipe 5 and fitting 1 into the outlet pipe 8. Therefore it will be seen that a simple and durable outlet valve structure is provided and that the parts may be easily and readily manipulated for the purpose of permitting water to flow from an elevated tank or receptacle.
